CentOS Atomic host少し触ってみた

参考

• Atomic: /usr/bin/atomic — Project Atomic

atomicコマンドの使い方

atomic run ntpd

index.docker.ioに接続できない場合は数分待てば解決した

• can't reach index.docker.io · Issue #3203 · docker/docker

できない？？

-bash-4.2# atomic run ntpd
Trying to pull repository docker.io/ntpd ... not found
FATA[0004] Error: image library/ntpd:latest not found

ネットには繋がってるよな・・・

-bash-4.2# ping google.co.jp

やはりダメか

-bash-4.2# docker pull ntpd
Trying to pull repository docker.io/ntpd ... not found
FATA[0003] Error: image library/ntpd:latest not found

環境変数の MIRROR_SOURCE, MIRROR_SOURCE_INDEXを変更すればよかったのかも。

5分待った結果

成功

-bash-4.2# docker pull nginx
